We are porting a display-project from Imagecraft-compiler to IAR-compiler for the STM32F446-chip. This is the most vital bits of the LDC-drive (with ILI9488-chip). The pins are alive, checked by an oscilloscope (we don't have a logic analyzer) and th...

Thanks clive1,now we got it to work! 

Hello, Sorry for delay in answer.We don't know how to do that. Could you give example of how to call HAL_UART_IRQHandler?

Great thanks, now it works!!!!Regards Ricard

Porting display project. It works with image crafts compiler But not with IAR compiler. Any ideas what the problem be?

Why does the first debug-usart-init work and not the second?

Why doesn't receiver-interrupt work on UART4 in this example when it works for USART1 and USART3?

We are trying to get UART-receiver to work in interrupt mode.

Trying to learn the STcube/HAL-interfaces on a NUCLEO-F446RE but got stuck at a very basic level. To control a pin (LED) worked well but trying to read the button-pin (PC13) doesn't seem to work. Though an example with interrupt on that pin work. See ex.
